This paper describes the authors? experiences creating a full Build Management System from a simple Version Control System. We will explore how the XP values of simplicity, feedback, communication, courage and respect play into making a system that provides the developers, testers and customer with excellent value showing how various XP principles (like Baby Steps and Mutual Benefit) come into play. We will also demonstrate how we are able to remain true to our XP values while still achieving ISO 9001- 2001 and CMM Level II certifications. Finally, we compare the Build Management System with other systems we have encountered that were not developed in accordance with XP values.
